What This Product Does

The filler neck provides the route between the refuelling opening and the tank connection. It is distinct from the filler cap, protective flap and adjoining hoses, which have separate roles within the assembly.

Functions

• Directs fuel towards the tank when filling.
• Forms part of the vehicle's fuel-filling assembly.
  
  

Technical Details

• Supplied part reference: 90120105120.
• Brand: OE Match.
  
  

Symptoms of Fault

• Petrol odour concentrated around the filling opening.
• Dampness or fuel marks surrounding the neck and its connections.
• Visible deterioration affecting the filler assembly.
  
  

These signs can also originate from the cap seal, connecting hose or breather connections. Inspect the surrounding components before deciding which part requires renewal.

Why Replacement Matters

Renewing a damaged filler neck addresses deterioration in the refuelling passage. Check adjoining hoses, seals and clamps during the work, as replacing the neck alone will not resolve leakage from another component. OE Match focuses on Porsche replacement applications, using original references and vehicle specifications to guide component selection.

FAQs

Does a petrol smell confirm that the neck has failed?
No. The cap seal, filler hose and breather connections can produce similar symptoms; identify the source first.

Should the clamps also be renewed?
Inspect their condition and replace any that are corroded, damaged or unable to secure the connection correctly.

What should be checked before ordering?
Compare reference 90120105120, the vehicle's production year and the existing assembly, particularly where the supplied application periods overlap.
